The global limitation of fossil fuels impels scientists to search for new energy sources. A good alternative is biodiesel produced from crop plants. However, its production requires huge quantities of farmland, fertilizers and fresh water, which is in conflict with the human demand for water for consumption and land for food production. Thus, production of single cell oil (SCO) by oleaginous microorganisms remains the best solution for the coming years. Whereas most microorganisms require fresh water for proper cell metabolism, in this study we demonstrate that the unconventional yeast is able to produce huge quantities of fatty acid in seawater-based medium. Here we shown that is able to produce fatty acids in medium based on seawater and crude glycerol as the main carbon source, which allows for low-cost production of SCO, is beneficial for industrial application and is ecologically friendly.
全球范围内化石燃料的限制促使科学家寻找新的能源。一个不错的替代方案是用农作物生产生物柴油。然而，其生产需要大量的农田、化肥和淡水，这与人类对消费用水和粮食生产用地的需求相冲突。因此，未来几年，由产油微生物生产单细胞油（SCO）仍是最佳解决方案。鉴于大多数微生物需要淡水来进行正常的细胞代谢，在本研究中我们证明，这种非常规酵母能够在以海水为基础的培养基中大量生产脂肪酸。在此我们表明，（此处原文缺失具体酵母名称）能够在以海水和粗甘油为主要碳源的培养基中生产脂肪酸，这使得单细胞油能够低成本生产，有利于工业应用且生态友好。
